4 Claims.

1 The present invention relates to improvements in razors, and moreparticularly to the type of razor which is provided with a vibratorwhereby the shaving action will be greatly improved.

An object of the present invention is to'provide a novel structure forholding a double edge conventional razor blade and wherein a vibrator isprovided for flexing the razor blade to effect more eificient cutting bythe edges of the blade during shaving.

Another object of the present invention is to provide a novelarrangement whereby the razor blade is detachably secured to the handleof the razor and wherein novel latching means are provided for effectingthe detachable securing of the razor blade within the razor bladeholder.

Still other objects or the present invention are to provide such meansthat are simple in construction, economical of manufacture and readilyassembled. I

Various other objects and advantages will become apparent from thedetailed description to follow. The best form in whichI havecontemplated applying my invention is clearly illustrated in theaccompanying drawings wherein: Figure 1 is a side elevational view ofthe razor with parts in section;

Figure 2 is a bottom plan view of the upper arcuated plate showing arazor blade mounted thereon; v

Figure 3 is a, transverse sectional view taken substantially alongtheplane of line 3-3 of Figure 1;

Figure 4 is a vertical longitudinal sectional view taken substantiallyalong the plane of line 4--4 hollow portion 28 in which a solenoid 22 isprovided, the solenoid 22 being of conventional form as is common invibrators. The handle I4 has a reduced extension portion 24 which isaxially bored at 26.

The holder means 16 for the razor blade 28 is comprised of a pair ofarcuated plates 30 and 32 which are disposed in opposing relation toeach other. The outer plate 30 is provided with a pair of downwardlyextending flat elements 34 and 36 which are adapted to pass through cutouts in the conventional razor blade 28 and extend through slots in thelower arcuated plate 32 at 38 and at 40. Each of the downwardlyextending flat elements 34 and 36 is provided with a cam slot 42. Thelower arcuated plate 32 is substantially of conventional form having theouter longitudinally extending lip portion 44 for overlying the sharpedges of the razor blade 28. The outer arcuated plate 30 is alsoprovided with a centrally disposed pin 46 which is adapted to extendthrough the cut out of the razor blade 28 at the central portionthereof.

A plunger 48 is reciprocably disposed within the bore 26 of the handleI4 and has a lower end portion reciprocably disposed within the solenoid22 for vibration thereby. The plunger 48 is provided with a pair ofmetallic disks 50 and 52 on either side of the rubber ring 54 formaintaining the plunger 48 in axial alignment within the handle I 4. Theouter end of the plunger 48 is provided with an enlarged head portion 56which has an arcuated surface 58 for engagement with the under side ofthe razor blade 28. The enlarged head 56 is also provided with a recess68 for receiving the pin 46 of the outer arcuated plate 30. As seen bestin Figure 3, the plunger 48 has a squared portion 62 for cooperationwith a non-circular bore extension 64 of the handle [4. Thus, theplunger 48 will be maintained in desired relation to the, arcuatedplates 30 and 32 so that the arcuated surface 58 will engage the razorblade 28 as desired.

Looking now at Figures 3 and 4, it will be seen that the latching meansI8 is comprised of a bushing 66 having an outer knurled surface, thebushing 66 being rotatably disposed on the reduced handle portion 24.The bushing 66 is provided with an annular flange portion 68 to which apair of latch bars 18 and 12 are pivotally secured, as at 14 and 16 bythe pin. Each of the latch bars 18 and 12 is provided with an elongatedslot 18 and 80. A pair of pins 82 and 84 are secured to the under sideof the arcuated plate 32 and extend downwardly through the elongatedslot 18 and 80. The outer ends of the latch bars 10 and 12 are arcuatedat 86 and 88 for engagement within the cam slots 42.

From the foregoing description, taken in con- Junction with thedrawings, it is believed that the operation of the razor will be readilyapparent to one skilled in the art. When the vibrator 22 is actuated,the plunger 48 will be rapidly reciprocated by the flexing of the razorblade 28 so that the cutting edges will rapidly reciprocate to improvethe cutting action thereby.

When it is desired to change the razor blade, the bushing 66 is rotatedso that the latch bars and 12 are removed from engagement with the camslots 42, The outer arcuated plate may then be removed and a new bladeinserted. After the outer arcuated plate is replaced, the bushing may berotated in the opposite direction to effect latching of the razor forfurther use.

Having described the invention, what is claimed as new is:

l. A razor comprising a hollow handle, razor blade holding means havingopposing upper and lower reversely arcuated plates, said lower platebeing secured to said handle, a solenoid disposed in said handle, aplunger disposed in said handle and vibrated by said solenoid, anenlarged head on said plunger of substantially the same length as saidblade holding plates and having spaced slots therein, said head beingdisposed between said plates, latch means detachably securing saidplates together whereby a razor blade may be inserted between saidplates and be engaged by said head, said latch means comprising spaceddownwardly extending flat lugs having cam. slots there,- on dependingfrom said upper plate and through said slots in said head, complementalslots in said lower plate through which said elements extend, and.further means associated with said handle, lower plate and cam slotsfor securing said plates together.

2. A razor comprising a hollow handle, razor blade holding means havingopposing upper and lower reversely arcuated plates, said lower platebeing secured to said handle, a solenoid disposed in said handle, aplunger disposed in said handle and vibrated by said solenoid, anenlarged head on said plunger of substantially the same length as saidblade holding plates and having spaced slots therein, said head beingdisposed between said plates, latch means detachably securing saidplates together'whereby a razor blade may bev inserted between saidplates and be engaged by said head, said latch means comprising spaceddownwardly extending fiat lugs having cam slots thereon depending fromsaid upper plate and through said slots in said head, complemental slotsin said lower plate through which said elements extend, and furthermeansassociated with said handle, lower plate and cam slots for securingsaid plates together, said further means including a bushing rotatablymounted on said handle, spaced slotted arms pivoted to said bushing,depending lugs on said lower plate guidingly engaging said arms by meansof the slots therein, end portions of said arms engaging the cam slotsof the downwardly extending elements upon rotation of said bushingthereby securing said plates together.
